Contrasts of hot rolled and cold rolled aluminum coil
Aluminum coil, also named as aluminum roll, according to the method of producing process treatment, it can be divided into two type, hot rolled aluminum coil and cold rolled aluminum coil . When it comes to how to make sure the product type we need, the difference of hot rolled aluminum coil and cold rolled aluminum coil should be get. The difference between the hot rolling aluminum coil and cold rolling aluminum coil: First compared from aluminum coil production process, after the aluminum ingot melt, coupled with the metallic elements, heating 12-15 hours, again flue into the crystallization pool extract impurities, after cooling, peel the top layer of impurities. For heating oven heat preservation, the temperature should be controlled between 450-520 degrees, heat preservation for 12 to 15 hours, and then flue into the crystallization in the pool, here is the different beginning of hot rolled and cold rolled aluminum coil , the hot rolling aluminum coil is pressure rolling by mill...
